In the field of advanced manufacturing, cleaning aluminum alloy components has long presented numerous challenges.
Complex geometries, fine cavities, and the risks of foaming or corrosion under high pressure all place stringent demands on cleaning agent performance.
Nanjing Kerun Industrial Media Co., Ltd. proudly introduces the KR-V500 water-based aluminum alloy cleaner, designed to deliver a breakthrough in the cleaning process with powerful decontamination, low-foam stability, excellent corrosion inhibition, and ultra-low residue.
PART 01｜Pain Points and Challenges — From “Not Clean Enough” to “Clean but Problematic”
In aluminum alloy component cleaning, traditional cleaning agents often face a range of persistent challenges:
• Incomplete cleaning on complex geometries – residual oil remains in deep holes, gaps, and fine surface textures.
• Excessive foaming under high pressure – prevents the cleaning fluid from effectively contacting the surface and may cause tank overflow.
• Corrosion, discoloration, and surface dullness – the aluminum surface may lose luster or turn yellow after cleaning.
• Watermark and residue formation – transparent stains may appear after immersion, affecting surface appearance and finish quality.
These problems are particularly evident in automotive, die-casting, and aerospace components, where they directly impact production efficiency and final product yield.

PART 02 Product Highlights – The Four Dimensions of KR-V500 Performance
1. Powerful Degreasing · Precise Separation
KR-V500 adopts an efficient composite surfactant system that removes complex oil contaminants through adsorption, roll-off, and emulsified dispersion mechanisms.
This enables complete degreasing and ensures a thoroughly clean surface ready for subsequent processing.
2. Low-Foam Control · Stable Under Pressure
Even under high-pressure spraying or ultrasonic cleaning conditions, KR-V500 maintains stable and controllable foaming behavior.
This significantly reduces the risk of tank overflow, ensuring both cleaning efficiency and operational safety.
3. Corrosion Inhibition · Bright and Clean Finish
Formulated with a specialized composite corrosion-inhibitor system, KR-V500 effectively prevents yellowing, graying, and secondary corrosion of aluminum alloy surfaces.
It restores and preserves the natural metallic luster after cleaning, keeping parts bright and smooth.
4. Ultra-Low Residue · Spot-Free Surface
Compared with competing products, KR-V500 leaves no visible marks or water stains on cleaned aluminum panels — achieving truly trace-free cleaning and zero residue for superior surface quality.
PART 03 Real Validation – Customer Case Demonstrating High Efficiency
A listed automotive components manufacturer adopted KR-V500 in its cleaning line for aluminum alloy and cast-iron cylinder sleeves.
Cleaning Object: Engine cylinder block
Cleaning Process:
Cleaning with KR-V500 (2.5%, 50 °C) → Tap water rinse 1 (50 °C) → Tap water rinse 2 (52 °C) → Air blow-off → Drying (63.7 °C)
Cleaning Method: Spraying process
After cleaning with KR-V500, the surface color appeared slightly darker, with uniform gloss and consistent appearance, meeting the cleanliness and quality requirements for precision automotive parts.
